Daisy is going 12 mph and sally is going 8 mph if they where 60 miles apart how many hours would it take for them to meet up

3 hours

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed in mph

d -----> the distance in miles

t ----> the time in hours

x ----> distance traveled by Daisy to the meeting point

60-x ----> distance traveled by Sally to the meeting point

so

Solve for d

Distance traveled by Daisy to the meeting point

we have

substitute

----> equation A

Distance traveled by Sally to the meeting point

we have

substitute

----> equation B

substitute equation A in equation B

solve for t

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
